Version 1 of the Hubble Source Catalog (HSC) is scheduled for release in February, 2015. The HSC combines tens of thousands of single visit-based WFC3, ACS, and WFPC2 source lists from the Hubble Legacy Archive (HLA) into a single master catalog with roughly 100 million individual sources, hence providing entry into the field of database astronomy. Searches that would require months or years to perform in the past can, in many cases, be done in seconds with the HSC. This resource may be used to support a wide range of new archival proposals, a few potential examples of which are listed in Section 7.4 (e.g., variability over more than a 20 year lifetime; in many cases, astrometry with better than 10 mas accuracy; cross-matching with a wide variety of catalogs). Currently, a Beta 0.3 version of the HSC is available to support exploratory projects.
